一定量的放射性物质作用于机体后,可以引起急性或慢性射线病,严重的可以致死。在射线病中天然免疫力下降,细菌感染成为死亡的主要原因之一。我们用 X 线照射家兔以观察其对副伤寒感染的影响。家兔绝食一昼夜后,饲以牛奶,奶中混入培养一昼夜的副伤寒菌(鼠伤寒杆菌),可以使之感染,与人类感染一样地发生菌血症,体温升高,肠道功能紊乱,白血球减少,凝集素升高,粪便带有鼠伤寒杆菌,尸体脏器中有病原菌。口服剂量为1仟万菌体,使兔发病而不死亡。如菌数为10亿或7亿5仟万,家兔全部死亡,如为5亿、1亿、5仟万、2仟5百万菌体,可使部分动物死亡。
A certain amount of radioactive material acting on the body, can cause acute or chronic ray disease, severe can be lethal. In the ray disease natural immunity is reduced, bacterial infection has become one of the main causes of death. We irradiated the rabbits with X-rays to observe their effects on paratyphoid infection. Rabbits hunger strike a day and night, fed with milk, milk mixed with day and night paratyphoid bacteria (Salmonella typhimurium), can make it infected, as with human infection bacteremia, body temperature, intestinal disorders, white blood cells Reduce lectin, stool with Salmonella typhimurium, pathogenic bacteria in the body organs. Oral doses of 1 million bacteria, so that the incidence of rabbits without death. If the number of bacteria is 1 billion or 750 million, all the rabbits died, such as 500 million, 100 million, 5 million, 2 5 million bacteria, can make some animals dead.
